As homeowners and landscapers seek sustainable and low-maintenance alternatives to traditional lawns, microclover lawns have become popular. Microclover, a smaller white clover, is often mixed with grass to create a lush, green lawn that offers several ecological and practical benefits. However, like any landscaping choice, microclover lawns come with their own set of pros and cons. In this comprehensive article, we’ll explore the advantages and disadvantages of micro clover lawns, provide detailed comparisons, and help you decide whether this type of lawn is right for you.

Overview: What is a Microclover Lawn?

A microclover lawn is a type of grass lawn that includes a significant proportion of microclover. Unlike traditional clover, micro clover is bred explicitly for lawn use, offering a finer texture and a more uniform appearance. When integrated into a grass lawn, micro clover can create a dense, green carpet that remains vibrant throughout the growing season.

Microclover lawns have become increasingly popular due to their eco-friendly attributes and ability to reduce the need for chemical fertilizers. But before you make the switch, it’s essential to understand the complete picture of what microclover lawns entail.

A Closer Look at Microclover

Before discussing the pros and cons, let’s examine what makes microclover unique and why it’s a beneficial addition to lawns.

What is Microclover?

Microclover (Trifolium repens var. ‘Pirouette’ or ‘Nano’) is a smaller, more refined version of the traditional white clover plant. It is characterized by:

• Smaller Leaves: Microclover leaves are tiny, typically one-third the size of regular clover leaves, making them less visually dominant when mixed with grass.
• Low Growth Habit: Microclover grows close to the ground, blending seamlessly with grasses and creating a uniform lawn surface.
• Nitrogen-Fixing Ability: Like other clovers, clover can fix nitrogen in the soil, enriching it naturally and reducing the need for synthetic fertilizers.
• Resilience: Microclover is drought-tolerant and can withstand heavy foot traffic, making it an excellent choice for frequently used lawns.

The Pros of Microclover Lawns

There are several advantages to incorporating micro clover into your lawn, many of which are rooted in sustainability and lawn health. Here’s a detailed look at the benefits:

Natural Fertilization

• Nitrogen Fixation: Microclover naturally fixes nitrogen from the air into the soil, which benefits the surrounding grass. This reduces or eliminates the need for chemical fertilizers, promoting a more organic approach to lawn care.
• Healthier Soil: Microclover’s presence can lead to richer, healthier soil over time, as it continuously replenishes nitrogen levels.

Drought Tolerance

• Reduced Water Needs: Microclover is highly drought-tolerant.
• Resilience: Unlike grass, which can turn brown and dormant during drought, microclover retains its green color and continues to grow, ensuring your lawn looks lush year-round.

Low Maintenance

• Less Mowing: Microclover’s low growth habit requires less frequent mowing than traditional grass lawns. This can save time and effort while reducing the environmental impact associated with lawn care.
• Fewer Chemicals: With its natural ability to enrich the soil and suppress weeds, microclover lawns require fewer herbicides and fertilizers, contributing to a more sustainable and eco-friendly lawn care regimen.

Weed Suppression

• Dense Growth: Microclover forms a thick mat that crowds out weeds, reducing the need for chemical weed killers.
• Competition: Its competitive nature means that it can outcompete many common lawn weeds, leading to a cleaner, more uniform lawn surface.

Aesthetic Appeal

• Year-Round Greenery: Microclover lawns maintain their vibrant green color throughout the year, offering an aesthetically pleasing alternative to grass lawns that may brown in the summer heat.
• Uniform Appearance: When adequately mixed with grass, microclover provides a smooth, even lawn surface that is soft to the touch and visually appealing.

Environmental Benefits

• Biodiversity: Microclover lawns promote biodiversity by providing a habitat for pollinators like bees and other beneficial insects.
• Reduced Carbon Footprint: By reducing the need for frequent mowing, watering, and chemical fertilizers, microclover lawns contribute to a lower carbon footprint.

The Cons of Microclover Lawns

Despite its many advantages, micro clovers are not without downsides. Before you decide to incorporate it into your lawn, consider the following potential drawbacks:

Initial Establishment

• Seeding Challenges: Establishing a microclover lawn can be tricky, especially starting from scratch. Microclover seeds are tiny and may require special care to ensure they germinate and establish properly.
• Cost: High-quality micro clover seed mixes can be more expensive than traditional grass seed, potentially increasing the initial investment required to establish your lawn.

Not Ideal for All Climates

• Temperature Sensitivity: Microclover thrives in temperate climates but may struggle in extreme heat or cold. It can go dormant in scorching climates; in cold climates, it may not survive harsh winters.
• Frost Sensitivity: Microclover is more sensitive to frost compared to some grass species, which can result in patchy areas after a cold winter.

Uneven Appearance

• Mixing Issues: If micro clover isn’t evenly mixed with grass, it can create an uneven appearance, with patches of clover dominating certain areas. This can detract from the uniform look many people desire on a lawn.
• Seasonal Variation: Microclover can sometimes grow faster than the surrounding grass, leading to a patchy appearance during certain times of the year.

Bee Attraction

• Flowering: While microclovers do not flower as prolifically as regular clovers, they can still attract bees when they bloom. This can concern those with bee allergies or homeowners who want to avoid attracting insects to their lawns.
• Increased Pollinator Activity: While beneficial for the environment, increased bee activity may not be desirable in all settings, particularly in areas where children play.

Requires Occasional Overseeding

• Maintaining Density: Microclover may require occasional overseeding to maintain its density and prevent bare spots, especially if it is subject to heavy wear or harsh weather conditions.
• Labor-Intensive: Overseeding can be labor-intensive and may need to be done every few years to keep the lawn looking its best.

Potential for Invasiveness

• Spreading: Microclover can spread beyond its intended area, potentially invading flower beds, gardens, or neighboring lawns. While it is not as aggressive as some other plants, its tendency to spread can become problematic if not properly managed.

Tips for Establishing and Maintaining a Microclover Lawn

Successfully establishing and maintaining a micro clover lawn requires some knowledge and effort. Here are some tips to help you get started and keep your lawn looking its best:

Seed Selection

Choose a high-quality microclover seed mix suited to your climate and soil conditions. Look for varieties like ‘Pirouette’ or ‘Nano’ specifically bred for lawn use.

Soil Preparation

Before seeding, ensure that your soil is well-prepared. Microclover prefers well-drained soil with a neutral pH.

Seeding Technique

For best results, seed your lawn in early spring or fall when temperatures are moderate. Use a broadcast spreader to ensure the seeds are distributed evenly.

Watering

Once established, microclover lawns require less water than traditional grass lawns. Occasional deep watering may be necessary to keep the lawn looking lush.

Mowing

Mow your microclover lawn less frequently than a traditional grass lawn. Mowing every three to four weeks is typically sufficient.

Overseeding

To maintain the density and health of your micro clover lawn, consider overseeding every couple of years. This helps fill bare spots and ensures the clover thrives alongside the grass.

Weed Management

While microclover naturally suppresses many weeds, some may still manage to grow. Hand-pull any weeds that appear, especially in the early stages of lawn establishment. Avoid using broadleaf herbicides, as they can harm the microclover.

Dealing with Flowering

If you’re concerned about attracting bees, mow your lawn just before the microclover begins to flower. This will reduce the number of blossoms and, consequently, the number of bees.
